Teresa Fox and Arwyn Birch sell only doughnuts and Intelligentsia coffee and espresso at their new Glam Doll Donuts shop in the heart of Eat Street. But they obviously put the rest of their planning energy into the interior design, with its hand-painted tiles, original artwork, vintage photo booth, and comfy seating. The doughnuts lean toward unconventional combinations like a peanut-buttery cake doughnut with sweet-spicy sriracha glaze or a raised turnover filled with muenster and provolone cheeses topped with curry icing. But you'll find straight-up classics too: apple fritters, plain icing with sprinkles, and doughnuts filled with raspberry curd. But what really sets Glam Doll apart is its hours: It's open till 1 a.m. Thursday through Saturday.
